Based on his speed and the distance driven within that time, Kwan will have driven 144 miles in 2 hours

First find out Kwan's speed per hour:

Speed = Distance / Time

Convert the time to decimals:

= 1 + 1/4 hours

= 1 + 0.25

= 1.25 hours

Speed:

= 90 / 1.25

= 72 miles per hour

In 2 hours therefore, Kwan would have gone:

= 72 x 2 hours

= 144 miles

In conclusion, Kwan would have driven 144 miles.

The distance kwan drive in 2 hours at this rate is known as 144 miles

Given that kwan is driving at a constant speed after 1/1/4 hours he has driven a total distance of 90 miles, this can be expressed as:

90 miles = 1 1/4 hours

To determine the total distance covered in 2 hours, this can be expressed as;

x = 2hours

Divide both expressed as:

90/x = (1 1/4)/2

90/x = (5/4)/2

90/x = 5/8

5x = 8 * 90

5x = 720

x = 720/5

x = 144

This shows that the distance kwan drive in 2 hours at this rate is known as 144 miles
