A train leaves at 13.23 and arrives at its destination at 14.05. If the train travelled 31 km, what was it's average speed in km/h? Give your answer rounded to 1 dp.

0.738 km/h

Step-by-step explanation:

It took 42 minutes from takeoff to get to its destination, so when you divide 31/ 42 (42 representing the time and 31 km representing the distance), you get 0.738 km/h

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

answer: 0.64
