Question

Tigran drove 2/5 of a 150-mile trip in the first hour of driving. in the second hour of driving, he traveled 5/6 of the remaining miles. what part of the whole trip did Tigran travel during these two hours?

Answer 1

Answer:

Let us assume that Abdul is travelling x kilometer distance while going to school.

Distance = Speed x Time

1)When it's average speed is 20 km/hr

x=v1×t1=20×t1

2)When it's average speed is 30 km/hr

x=v2×t2=30×t2

Vaverage=totaltimetakentotaldistancetravelled

Vaverage=v1x+v2xx+x=20x+30x2x=24 km h−1

Answer 2

Answer:

Tigran Drove 3/5 of the whole trip.

Step-by-step explanation:

First find 2/5 of 150 =>

2/5 of 150 = 60

Now, it says '5/6 of the remaining miles'

The remaining miles is 90 and we know this becuase:

150 - 60 = 90

Now, we find 5/6 of 90 =>

5/6 of 90 = 75

We now know it is 75/150 miles that Tigran has driven, but we need to simplify this anwer.

75/150 in simplest form is 3/5

Tigran drove 3/5 of the trip during these two hours.
