Please help...even if you answer one I will give you a helpfulrating...if you answer in 2 responses one for each I will rate youtwice...if you answer both I will rate you a lifesaver and helpful9 points. (a) A plane whose air speed is 150 mi/h flew from Abbot toBlair in 2 h with a tail wind. On the return trip against the samewind, the plane was still 60 mi from Abbot after two hours. Findthe wind speed and the distance bewtween Abbot and Blair. (b) While training for a biathlon race, Kevin covered a totaldistance of 9 km by swimming for 45 min and running for 20 min. Thenext day he swam for 30 min and ran for 40 min, covering 14km. Find his rates (in km/h) for swimming and running.(assume that these rates are constant.)

let swimmng rate is v km/h and running rate V km/h so as distance = speed * time case 1 : 45 min swimming = (45/60 )hr = 0.75 hr 20 min running = 20/60 = 0.33 hr so 9= 0.75v + 0.33V case 2 : 30 min swimming = 30/60 = 0.5 hr 40 min running = 40/60 = 0.67 hr so 14 = 0.5v + 0.67V
