Adistance of 150 km was covered by a motorcyclist traveling at a average speed of 75 km/h by a bus 60 km/h a truck at 50 km/h and a bicyclist at 20 km/h how much time did it require to travel the entire distance

The time required to travel the entire distance is 2.93 hour.

Step-by-step explanation:

Given that,

Distance = 150 km

Speed of motorcyclist = 75 km/h

Speed of  bus =60 km/h

Speed of truck = 50 km/h

Speed of bicyclist = 20 km/h

We need to calculate the average speed

Using formula of average speed

Put the value into the formula

We need to calculate the time

Using formula of speed

Where, D = total distance

t = time

Put the value into the formula

Hence, The time required to travel the entire distance is 2.93 hour.

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).

x > 4

step-by-step explanation:

solve for   x by simplifying both sides of the equation, then isolating the variable.
