Answer:
A) speed = 10.5 miles per hour
B) Time taken by him = 1.714 hours
C) Distance = 10.5 mph × 7 hours = 73.5 miles
Step-by-step explanation:
Given as :
The distance cover by David = miles = 5.25 miles
The time taken by David = hours = 0.5 hours
Let the speed = x mile per hour
So, Distance = Speed × Time
A)or, Speed =
Or, Speed =
∴ speed = 10.5 miles per hour
<u>B) Again The Distance cover by him = 18 miles</u>
SO, with speed 10.5 miles per hour
The Time taken by him = hours
Or, Time taken by him = hours
∴ Time taken by him = 1.714 hours
<u>C) Again the Time taken by him = 7 hours </u>
So, Distance cover by him with speed 10.5 mph
Or, Distance = 10.5 mph × 7 hours = 73.5 miles
A) speed = 10.5 miles per hour
B) Time taken by him = 1.714 hours
C) Distance = 10.5 mph × 7 hours = 73.5 miles Answes
