Question

Teru burned about 1,000 calories downhill skiing before lunch. If she plans to ski

for a total of 5 hours today, how many hours will she ski after lunch?

Answer 1

3.3333 hours

Explanation:

From the attached table :

Downhill skiing for 1/6 hours ; results in 100 calories burn

To burn 1000 calories :

Skiing hours required :

(1000 / 100) * (1/6)

10 * 1/6 = 10 /6 hours

Planned skiing hours = 5

Number of skiing hours after lunch will be :

5 hours - 10/6 hours

5 hours - 1.6666 hours

= 3.3333 hours
