Answer:
9:45 AM
Explanation:
To get to work in the morning, Amanda cycles for 10 miles at the rate of 12 mph.
Time (hours) = Distance/speed
Hence, the time she spends cycling = 10mile/12 mph
= 0.8333333333 hour
Converting to minutes:
1 hour = 60 minutes
0.8333333333 hour =
0.8333333333 hours × 60 minutes/1 hour
= 50 minutes.
Hence, she spends 50 minutes cycling
She makes a 10 minutes stop for a cup of coffee, and then rides a bus for 15 minutes. The speed of the bus is 45 mph.
The total number of minutes she spends to get to work is calculated as:
(50 + 10 + 15)minutes
= 75 minutes.
It takes Amanda 75 minutes to get to work.
At what time will Amanda get to work if she leaves home at 8:30 AM?
= 8:30AM + 75 minutes
= 8:30 AM + 1 hour 15 minutes
= 9:45 AM
