Step-by-step explanation:
First let us suppose the missing number x
I think we will cross multiply
5b2 = bx
5b2/b = bx
5b = x
Answer:
s = 3.75 miles/hour
Step-by-step explanation:
Distance covered = 1/4 of a mile
Time taken = 1/15 of an hour
We need to find the speed of the track. We know that,

So, the required speed is 3.75 miles/hour.

6:5
x:45
x = (45/5) x 6
45/5 = 9
9 x 6 = 54
there are 54 boys in the choir
Answer:
The rate of car travel is 5.2 kilometers per minute.
Step-by-step explanation:
We are given the following in the question:
Total time of travel = 22 minutes
Total distance covered = 114.4 kilometers
We have to find the rate at which the car is travelling.
Formula:
Rate, r

where d is the distance covered and t is the time.
Putting values, we get,

Thus, the rate of car travel is 5.2 kilometers per minute.
