average speed= total distance/total time taken

60+45= 105miles

1 mile= 1.609

105×1.609= 168.945km

168.945/4

Hence answer = 33.79 km/hr

How many minutes will the bus take to complete the trip If a bus completes half a trip at 40 km per hour and the other half at 5

vlabodo [156]

Answer:

The bus will take 81 minutes to complete the trip.

Step-by-step explanation:

To determine how many minutes will the bus take to complete the trip if a bus completes half a trip at 40 km per hour and the other half at 50 km per hour, and the whole trip was 60 km, the following calculation must be performed:

60/2 = 30

30/40 = 3/4 of an hour = 45 minutes

30/50 = 3/5 of an hour = 36 minutes

45 + 36 = 81

Therefore, the bus will take 81 minutes to complete the trip.

The top of blue mountain ski slope 19 3/4 yards above sea level. The lowest point of the ski point is 12.5 yards below sea level

lorasvet [3.4K]

Answer: 3.625 yards above the sea level.

Step-by-step explanation:

Given: The elevation of top of top of blue mountain above the sea level= $19\frac{3}{4}=19.75\ yards$

The length of the lowest point below the sea level= 12.5 yards

The total elevation from the lowest point under the sea and the top of blue mountain=19.75+12.5=32.25 yards

The midpoint between the top and bottom of the slope = $\frac{1}{2}\times32.25=16.125\ yards$

Since the ski lift is going to pick them up at the midpoint between top and bottom of the slope.

Therefore, the elevation at which they will be picked up= 19.75-16.125=3.625\ yards above the sea level.
