This distance-time graph represents a journey made by Sue. work out how much time Sue spends travelling and how much time she spends stationary

Sue spends travelling 3.5 hours and spends stationary 2.5 hours

Step-by-step explanation:

The attached image shows Sue's distance-time graph, from there we can observe the segments where she is stationary (lines with no slope) and the segments where she is travelling (lines with slope).

Time spent travelling:

From 2 p.m. to 3 p.m. is 1 hour

From 3:30 p.m. to 4 p.m. is 0.5 hour

From 5 p.m. to 6:30 p.m. is 1.5 hours

From 7:30 p.m. to 8 p.m. is 0.5 hour

Total time travelling=1 h+0.5 h+1.5h+0.5h=3.5 h

Time spent stationary:

From 3 p.m. to 3:30 p.m. is 0.5 hour

From 4 p.m. to 5 p.m. is 1 hour

From 6:30 p.m. to 7:30 p.m. is 1 hour

Total time travelling=0.5 h+1 h+1h=2.5 h

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
