57.1 km/ h

Step-by-step explanation:

First find the amount of time it took for Olly to drive from Liverpool to Manchester.

Time = Distance / Speed

= 56 / 70

= 0.8 hours

It took 75 minutes to drive from Manchester to Sheffield. In hours that it:

= 75 / 60 minutes

= 1.25 hours

Total time taken to travel from Liverpool to Sheffield is therefore:

= 0.8 + 1.25

= 2.05 hours

Distance travelled from Liverpool to Sheffield:

= Distance from Liverpool to Manchester + Distance from Manchester to Sheffield

= 56 + 61

= 117 km

Average speed for the whole journey is therefore:

= Distance / Time

= 117 / 2.05

= 57.1 km/ h

y= -

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
