Question

Iva wanted to train for a race by raning 10km over 3 days during the week. the first day she ran 1.37 km more than she ran on the second day. on the third day, she ran 0.98 km more than the second day. how many km she run on the third day ?

Answer 1

3.53 km

Explanation:

Let third day be X:

Second day: X - 0.98

First day: X - 0.98 + 1.37 = X + 0.39

X + X - 0.98 + X + 0.39 = 10

3X = 10.59

X = 3.53 kn
