Question

Duke swims 0.10 mile in 2 minutes. If he swims at the same speed, how many miles does Duke swim in a minute, written as a decimal?

Answer 1

If he swims .10 in 2 mins, half of that (one min) is .05

Answer 2

Answer:

since you know the amount he swims for 2 mins then divide that amount to get the amount for 1 minute. so 2=0.10 which means 1=0.5 since you halved it.

Hope this helps!
