Question

A typical walking rate is 1 mile in 20 minutes. If a jogger can jog about three times that speed, approximately how far would that jogger be able to jog in 2 hours

Answer 1

The jogger would be able to jog 18 miles in 2 hours

Explanation:

Here we want to know how far a Jogger can go in 3 hours given his speed rate.

We are told that he can work 1 mile in 20 minutes; So in 60 minutes(1 hour) he would have worked 3 * 1 mile = 3 miles

So his speed is 3 miles per hour

Now , his jogging speed is 3 times this, so his jogging speed will be 3 * 3 miles per hour = 9 miles per hour

So now we want to know how far he would have Jogged in 2 hours given the jog speed;

Mathematically;

distance = speed * time

Distance = 9 mph * 2 h = 18 miles
