Ответ:
The Total distance she travel fro work is 30 miles .
Step-by-step explanation:
Given as :
the total time taken to cover distance = 45 minutes
Let The total distance cover = D miles
The distance cover at the speed of 32 mph =
miles
The time taken to cover
miles distance =
hour
Distance = Speed × Time
∴
= 32 mph ×
h
or,
= 16 miles
Again ,
The distance cover at the speed of 56 mph =
miles
The time taken to cover
miles distance =
hour
∴
= 56 mph ×
h
or,
= 14 miles
So , The total distance she travel for work =
+ ![D_2](/tpl/images/0387/2257/17392.png)
Or, The total distance she travel for work = 16 miles + 14 miles = 30 miles
Hence The Total distance she travel fro work is 30 miles . Answer
