Ruben and Claire are training to run a marathon in the spring. Ruben runs 16 miles over a 4-day period. Claire runs 12 miles over a 3-day period. Are they running at the same rate of speed?

Answer 1

To determine if Ruben and Claire are running at the same rate of speed, we need to calculate their average speed.

Ruben runs 16 miles over a 4-day period, so his average speed is 16 miles / 4 days = <<16/4=4>>4 miles per day.

Claire runs 12 miles over a 3-day period, so her average speed is 12 miles / 3 days = <<12/3=4>>4 miles per day.

Both Ruben and Claire are running at the same rate of speed, which is 4 miles per day.
