Question

Grace biked for 8 miles in 1 hour on Monday. She covered 18 miles in 2 hours the next day. On which day did Grace bike at a faster pace? ​

Answer 1

The next day

Explanation:

she covered 8 miles in 1 hour on Monday but on tuesday she covered 9 miles in 1 hour so she biked faster the next day.

Answer 2

Note that:

• 
  `Speed = (Distance)/(Time)`

Find the speed of her bike of both the days and compare.

• Speed on Monday = 8 miles/1 hour = 8 m/h
• Speed on the next day = 18 miles/2 hours = 9 m/h

This means that:

• => 9 m/h > 8 m/h

Hence, the day after Monday is the day, she rode her bike faster than on Monday.
