Ajoba and Prav drive to work. Ajoba drives 45 miles in 2.5 hours. Prav drives 74 km in 1 hour 15 minutes. Work out the difference between their average speed in km/h. 1 mile = 1.6 km

Ajoba: 28.8km/h

Prav: 59.2km/h

The difference in speed is: 59.2-28.8=30.4km/h

Step-by-step explanation:

Ajoba:

d=45mi Convert to km //

t=2.5h

v=? 28.8km/h

Prav:

d=74km

t=1h15m or 1.25h

v=? 59.2km/h

Solve for v;

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
