Answer:
4 11/20
Step-by-step explanation:
Using bidMAs Multiplication comes first before addition
2/5 * 7/6 = 14/30
7/6 * 7/2 = 49/12
Make denominators equal
14/30 * 2 = 28/60
49/12 * 5 = 245/60
Then add
28/60 + 245/60 = 273/60
Finally convert improper into mixed fraction
4 11/20
25km east + 25km return+ 40km west + 40km return = 130km
