Question

Valentina is going for a bike ride. Below is a
distance-time graph that describes her full
journey
a) How long was she stationary for?
b) What was the total distance travelled during
her journey?​

Answer 1

Answer:

a) 7.5 min

b)50km

Explanation:

a) The time for which her y axis or distance was not moving or was constant was between 17:45 and 17:52 that is the time when she was in rest

b) Here the total distance travelled would be when she is moving that is when her y axis and x axis coordinates ( both ) are changing so the total distance is 50 km till 18:15.

25 km till 17:45 and another 25km till 18:15 also rest means distance not covered that is 0 km

=> (25+0+25) km

=> 50km

Answer 2

a)7.5m

b)50km

Explanation:

a) The time for which her y axis or distance was not moving or was constant was between 17:45 and 17:52 that is the time when she was in rest

b) Here the total distance travelled would be when she is moving that is when her y axis and x axis coordinates (both ) are changing so the total distance is 50 km till 18:15.

25 km till 17:45 and another 25km till 18:15 also rest means distance not covered that is 0 km
