Answer:

a) He will take 76 minutes in the triathlon

Explanation:

He runs 1/5 of a mile in 1/20 f hour then, by simple inspection

1/5 ⇒ 1/20 then 1/5 miles* 10 = 2 miles

1/20*hours*10 = 1/10 hours

10/10 of an hour is 60 minutes

1/10 of an hour is 6 minutes

swimming

1/3 of a mile in 1/9 of hours then

1/3mile *6 = 2 miles

1/9 of an hour * 6 = 6/9 hours or 2/3 of an hour

3/3 of an hour is 1 hour = 60 minutes

2/3 of an hour is = 40 minutes

In bike

4 miles in 1/4 hour then

4 miles *2 = 8 miles

1/4 hour* 2 = 1/2 hour = 30 minutes

Then he will do the triathlon in:

6 minutes running

40 minutes swimming

30 minutes in bike

Total 76 minutes
