Question

A car travels 1 mile in 75 seconds. At this rate, how many miles will the car travel in 1 hour?

Answer 1

Car will travel `48` miles in `1` hour

Explanation:

In `1` hour we have `60xx60=3600` seconds.

In `75` seconds, the car travels `1` mile,

so in `1` second it travels `1/75` miles and

in `3600` seconds, it will travel `1/75xx3600` miles

i.e `1/(3xx5xx5)xx(3xx3xx2xx2xx2xx2xx5xx5)` miles

= `1/(cancel3xxcancel5xxcancel5)xx(cancel3xx3xx2xx2xx2xx2xxcancel5xxcancel5)` miles

= `48` miles
