Charlie runs laps around a track. The table shows how long it takes him to run different numbers of laps. How long would it take Charlie to run 9 laps? chart:

Number of laps-- 2 4 6 8 10

Time (min)-- . . . .14 28 42 56 70

63 minutes

Step-by-step explanation:

If you look at each part of the chart, it takes 7 minutes per 1 lap. So, you would simply just multiply 9 by 7 which will give you your answer of 63.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
