Afamily is taking a cross-country trip by car. they drive at an average speed of 55 mi/h, and their goal is travel at least 400 mi/day. how many hours per day do they need to drive?

0.31hour

Step-byd-step explanation:

If a family drives at least 400mi/day, this means they drive at least 400mi/24hours since there are 24hours in a day.

Considering the expression;

If 400 miles = 1day which is also equivalent to 400 miles = 24hours

To get the amount of miles driven in an hour we have;

400miles = 24hours

x miles = 1hour

Cross multiplying we have;

400 × 1 = 24x

x = 400/24

x = 16.7miles

This means means they covered at least distance of 17 miles in an hour.

If their average speed is 55miles/hour.

The number of hours they need to drive per day can be calculated using the expression;

Speed = distance/time

Time = Distance in miles per hour/speed

Time = 17/55

Time = 0.31hour

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
