There are 450 calories in 100 g of trail mix. If you burn 30 calories in 10 minutes of walking, how much trail mix should you ea
irinina [24]

Answer:

to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

Explanation:

Firstly, let us calculate the number of calories burnt in 2 hours

in 10 minutes; 30 calories are burnt

∴ in 1 minute 30/10  calories are burnt = 3 calories are burnt

2 hours = 120 minute

∴ in 120 minutes 3 × 120 = 360 calories are burnt.

Next, let us calculate the amount of trail mix that contains 360 calories

100g of trail mix = 450 calories

450 calories = 100 g

1 calory = 100/450

∴ 360 calories = 360 × (100/450)

=  360 × 0.222 = 80g

∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten
