Question

Steve can complete the 100m dash in 10 seconds while Paul can run it in 12 seconds. How does Steve's time compare to Paul's?

A. Steve is 5⁄6 as fast as Paul
B. Steve is 1⁄2 as fast as Paul
C. Steve is 1⁄2 slower than Paul
D. Steve is 5⁄6 slower than Paul

Answer 1

Answer is A

Why:

Steve's speed is 100/10 or 50/5

Paul's speed is 100/12 or 50/6

if you calculate this by using gcd, you will see that steve is 5/6 faster than paul

Answer 2

Let

x---------> Steve's time

y--------> Paul's time

we know that

`x=10\ s\\y=12\ s`

`x < y` ------> Steve is faster than Paul

Divide x by y

`(10)/(12)=(5)/(6)`

therefore

the answer is the option

A. Steve is 5⁄6 as fast as Paul
