Question

72 km = 90 mins. 32 km = 40 mins. how many mins = 300 km?

Answer 1

375 minutes

Explanation:

72 km = 90 mins. 32 km = 40 mins. how many mins = 300 km?

72/90 = 0.8

32/40 = 0.8

so:

300/x = 0.8

multiply both sides by x:

x(300/x) = 0.8(x)

300 = 0.8x

divide both sides by 0.8:

x = 375
