Question

Problemas de práctica de la lección 2 1. Una ciclista anduvo 3.75 millas en 0.3 horas. a. ¿Qué tan rápido iba ella en millas por hora? b. A esa tasa ¿cuánto tiempo le tomará andar 4.5 millas?​

Answer 1

a) Speed: 12.5 mph

b) Time to walk 4.5 miles: 0.36 hours

How to solve

a) Speed:

Speed = Distance / Time

Speed = 3.75 miles / 0.3 hours

Speed = 12.5 mph

b) Time to walk 4.5 miles:

Time = Distance / Speed

Time = 4.5 miles / 12.5 mph

Time = 0.36 hours

Therefore, the cyclist's speed was 12.5 miles per hour, found by dividing the distance traveled (3.75 miles) by the time taken (0.3 hours). At this speed, walking 4.5 miles would take approximately 21.6 minutes.
