Answer:

Step-by-step explanation:

Time taken for task 1:

Distance= 750m= 0.75 km

Speed= 10 km/hr

Time taken1= S (distance)/ V (speed)= 0.75/10= 0.075 hr= 4 mins and 30 sec

Time taken for task 2:

t2=S/V= 20/85= 0.24 hr= 14 mins and 24 sec

Time taken for task 3:

t3= S/V = 5/14= 0.36 hr= 21 mins and 36 sec

Total time took:

T1 +T2+T3= 40 mins and 30 second (approximately)

Viefleur [7K]

Answer: [<em>b + 4 = -10</em>]

Step-by-step explanation: We are given the equation <em>b = -14</em> and told to, given this information, evaluate <em>b + 4 = ?</em> and find <em>?.</em> Given b = -14 we can plug in <em>-14</em> for <em>b</em> in <em>b + 4 = ?</em>.
