WINSTONCH [101]

Answer:

She rode 17.4 miles in 1 hour

Step-by-step explanation:

A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?

Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.?

The quotient is the average speed and this is calculated as:

Speed = Distance(miles)/Time(hours)

Where speed = quotient

Distance = Dividend

Time = Divisor

Speed = 60.9 miles/3.5 hours

= 17.4 miles/hour

Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!

If :

3.5 hours = 60.9 miles

1 hour = x miles

Cross Multiply =

3.5x = 60.9 miles

x = 60.9/3.5

x = 17.4 miles

Hence, she rode 17.4 miles in 1 hour
