) Asuka travels at an average speed of 50 mph for 20 miles. Without stopping, Asuka then travels 70 miles in 1.75 hours.
Find her average speed for the entire journey to 2 dp.

41.86 miles/hour

Step-by-step explanation:

Use Distance = Speed*Time to find the two missing values with the data that is provided for those two cases [in brackets].

MPHMILES     HOURS

 50            20      [0.4]

 [40]    70      1.75

Totals   90miles   2.15 hours

Average = 90 miles/2.15 hours

     41.86 mph

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
